Hi,

I have a data table as follows :

COLUMN A - Date
COLUMN B - Start
COLUMN C - Finish
COLUMN D - Total time

I need a formula to site in COLUMN L that will highlight (TRUE/FALSE) if there are overlaps in the times, specific to date.

THIS LIST IS SUBJECT TO SORTING AND SO THE FORMULA IN COLUMN F MUST USE OFFSET, or a full array to analyse the data and take into account the date.

e.g.

26/10/2009...09:00....13:00
26/10/2009...13:00....13:45
26/10/2009...13:40....16:00 overlap
26/10/2009...15:45....18:00 overlap
26/10/2009...18:15....19:00
27/10/2009...09:15....10:00
27/10/2009...10:00....13:00
27/10/2009...13:00....15:00
27/10/2009...15:00....16:00

Would be an amazing help!!!

Best regards

T

That's great, thanks!

Was almost there but not been using SUMPRODUCT for so long lost my touch!

Example data that breaks formula :

<TABLE style="WIDTH: 124pt; BORDER-COLLAPSE: collapse" cellSpacing=0 cellPadding=0 width=164 border=0><COLGROUP><COL style="WIDTH: 62pt; mso-width-source: userset; mso-width-alt: 2998" width=82><COL style="WIDTH: 62pt; mso-width-source: userset; mso-width-alt: 2998" width=82><TBODY><TR style="HEIGHT: 12.75pt" height=17><TD class=xl65 style="BORDER-RIGHT: #d8d8d8 0.5pt solid; BORDER-TOP: #d4d0c8; BORDER-LEFT: #d8d8d8 0.5pt solid; WIDTH: 62pt; BORDER-BOTTOM: #d4d0c8; HEIGHT: 12.75pt; BACKGROUND-COLOR: #f2f2f2" width=82 height=17>07:15</TD><TD class=xl66 style="BORDER-RIGHT: #d4d0c8; BORDER-TOP: #d4d0c8; BORDER-LEFT: #d8d8d8; WIDTH: 62pt; BORDER-BOTTOM: #d4d0c8; BACKGROUND-COLOR: #f2f2f2" width=82>08:30</TD></TR><TR style="HEIGHT: 12.75pt" height=17><TD class=xl65 style="BORDER-RIGHT: #d8d8d8 0.5pt solid; BORDER-TOP: #d4d0c8; FONT-WEIGHT: 400; FONT-SIZE: 10pt; BACKGROUND: #fac090; BORDER-LEFT: #d8d8d8 0.5pt solid; COLOR: black; BORDER-BOTTOM: #d4d0c8; FONT-FAMILY: Calibri; HEIGHT: 12.75pt; TEXT-DECORATION: none; mso-pattern: black none; text-underline-style: none; text-line-through: none" height=17>08:45</TD><TD class=xl66 style="BORDER-RIGHT: #d4d0c8; BORDER-TOP: #d4d0c8; FONT-WEIGHT: 400; FONT-SIZE: 10pt; BACKGROUND: #fac090; BORDER-LEFT: #d8d8d8 0.5pt solid; COLOR: black; BORDER-BOTTOM: #d4d0c8; FONT-FAMILY: Calibri; TEXT-DECORATION: none; mso-pattern: black none; text-underline-style: none; text-line-through: none">10:45</TD></TR><TR style="HEIGHT: 12.75pt" height=17><TD class=xl65 style="BORDER-RIGHT: #d8d8d8 0.5pt solid; BORDER-TOP: #d4d0c8; FONT-WEIGHT: 400; FONT-SIZE: 10pt; BACKGROUND: #f2f2f2; BORDER-LEFT: #d8d8d8 0.5pt solid; COLOR: black; BORDER-BOTTOM: #376091 0.5pt solid; FONT-FAMILY: Calibri; HEIGHT: 12.75pt; TEXT-DECORATION: none; mso-pattern: black none; text-underline-style: none; text-line-through: none" height=17>08:45</TD><TD class=xl66 style="BORDER-RIGHT: #d4d0c8; BORDER-TOP: #d4d0c8; FONT-WEIGHT: 400; FONT-SIZE: 10pt; BACKGROUND: #f2f2f2; BORDER-LEFT: #d8d8d8 0.5pt solid; COLOR: black; BORDER-BOTTOM: #376091 0.5pt solid; FONT-FAMILY: Calibri; TEXT-DECORATION: none; mso-pattern: black none; text-underline-style: none; text-line-through: none">18:00</TD></TR></TBODY></TABLE>

The bottom two should both be highlighted

<TABLE style="WIDTH: 124pt; BORDER-COLLAPSE: collapse" cellSpacing=0 cellPadding=0 width=164 border=0><COLGROUP><COL style="WIDTH: 62pt; mso-width-source: userset; mso-width-alt: 2998" width=82><COL style="WIDTH: 62pt; mso-width-source: userset; mso-width-alt: 2998" width=82><TBODY><TR style="HEIGHT: 12.75pt" height=17><TD class=xl67 style="BORDER-RIGHT: #d8d8d8 0.5pt solid; BORDER-TOP: #d4d0c8; FONT-WEIGHT: 400; FONT-SIZE: 10pt; BACKGROUND: #fac090; BORDER-LEFT: #d8d8d8 0.5pt solid; WIDTH: 62pt; COLOR: black; BORDER-BOTTOM: #d4d0c8; FONT-FAMILY: Calibri; HEIGHT: 12.75pt; TEXT-DECORATION: none; mso-pattern: black none; text-underline-style: none; text-line-through: none" width=82 height=17>07:15</TD><TD class=xl68 style="BORDER-RIGHT: #d4d0c8; BORDER-TOP: #d4d0c8; FONT-WEIGHT: 400; FONT-SIZE: 10pt; BACKGROUND: #fac090; BORDER-LEFT: #d8d8d8 0.5pt solid; WIDTH: 62pt; COLOR: black; BORDER-BOTTOM: #d4d0c8; FONT-FAMILY: Calibri; TEXT-DECORATION: none; mso-pattern: black none; text-underline-style: none; text-line-through: none" width=82>08:30</TD></TR><TR style="HEIGHT: 12.75pt" height=17><TD class=xl67 style="BORDER-RIGHT: #d8d8d8 0.5pt solid; BORDER-TOP: #d4d0c8; FONT-WEIGHT: 400; FONT-SIZE: 10pt; BACKGROUND: #fac090; BORDER-LEFT: #d8d8d8 0.5pt solid; COLOR: black; BORDER-BOTTOM: #d4d0c8; FONT-FAMILY: Calibri; HEIGHT: 12.75pt; TEXT-DECORATION: none; mso-pattern: black none; text-underline-style: none; text-line-through: none" height=17>08:45</TD><TD class=xl68 style="BORDER-RIGHT: #d4d0c8; BORDER-TOP: #d4d0c8; FONT-WEIGHT: 400; FONT-SIZE: 10pt; BACKGROUND: #fac090; BORDER-LEFT: #d8d8d8 0.5pt solid; COLOR: black; BORDER-BOTTOM: #d4d0c8; FONT-FAMILY: Calibri; TEXT-DECORATION: none; mso-pattern: black none; text-underline-style: none; text-line-through: none">10:45</TD></TR><TR style="HEIGHT: 12.75pt" height=17><TD class=xl67 style="BORDER-RIGHT: #d8d8d8 0.5pt solid; BORDER-TOP: #d4d0c8; FONT-WEIGHT: 400; FONT-SIZE: 10pt; BACKGROUND: #f2f2f2; BORDER-LEFT: #d8d8d8 0.5pt solid; COLOR: black; BORDER-BOTTOM: #376091 0.5pt solid; FONT-FAMILY: Calibri; HEIGHT: 12.75pt; TEXT-DECORATION: none; mso-pattern: black none; text-underline-style: none; text-line-through: none" height=17>07:15</TD><TD class=xl68 style="BORDER-RIGHT: #d4d0c8; BORDER-TOP: #d4d0c8; FONT-WEIGHT: 400; FONT-SIZE: 10pt; BACKGROUND: #f2f2f2; BORDER-LEFT: #d8d8d8 0.5pt solid; COLOR: black; BORDER-BOTTOM: #376091 0.5pt solid; FONT-FAMILY: Calibri; TEXT-DECORATION: none; mso-pattern: black none; text-underline-style: none; text-line-through: none">18:00</TD></TR></TBODY></TABLE>

Or in the above, all 3 should be highlighted

Hi

Try in D1:

=SUMPRODUCT(--((A1+C1<=$A$1:$A$15+$B$1:$B$15)+(A1+B1>=$A$1:$A$15+$C$1:$C$15)=0))<>1

Copy down

In this example I included the 6 cases from your last post at the end of your first table:


<table border="1" cellpadding="1" style="background:#FFF; border-collapse:collapse;border-width:2px;border-color:#CCCCCC;font-family:Arial,Arial; font-size:10pt" ><tr><th style="border-width:1px;border-color:#888888;background:#9CF " > </th><th style="border-width:1px;border-color:#888888;background:#9CF;

This is an excellent solution, however I need to expand upon it's capabilities a bit to make it work in my instance. This is where I fall short.

I have the date, arrive, and depart times but I am recording them for multiple truck routes in a fleet. I am trying to develop a QA procedure and need to be able to see whether, within the same route and day, there are time overlaps - which would indicate an error in data input.

</td> <td class="xl66" align="right">13:35</td> <td class="xl66" align="right">13:40</td> </tr> </tbody></table>

In this case, the first two rows times overlap and would reveal the data input error. I need to be able to test for overlap within route 3 and then within route 4, and then on and on for hundreds more routes.
Can this be done within standard excel or do I need a VBA solution? Thanks!!

Welcome to the MrExcel board!

Does this do what you want? You may need to change the "200"s in the formula before copying down. That number needs to be big enough the reach at least the last row of your data.

Not sure if I can ask in this thread as I am a new to here. I have this problem similar with the above discussions but the only different is that the overlapping time for particular product. How can I do this? Thanks for your help
